My invention pertains to certain 'novel and improved structural andfunctional betterments in Ventilated or cooled buffing-wheels and theirmountings, one leading object of the invention 5 being to provide a newtype of structure which more adequately controls the temperature of thefabric-elements of the wheel while in operation, and more particularlythe inner or middle portion of the wheel.

Another aim of the invention is to supply a buffing-wheel of the stylereferred to which is relatively simple in construction, and hencecomparatively economical to manufacture.

A further purpose of the invention is the provision of a buffing-wheelwhich is efiicient in operation and which is unlikely to become damagedor injured in ordinary serfice.

An added design or intention of the invention is the furnishing of ahurling-wheel which may be mounted on, and demounted from, itssupporting and operating spindle or shaft with ease and dispatch.

To enable those acquainted with this art to understand the inventionfully, two present desirable embodiments of the same have beenillustrated in the accompanying drawings to which reference should behad in connection with the following detailed description, and, forsimplicity, like reference numerals have been provided throughout theseveral views to designate the same parts of the construction.

In these drawings:

Figure l is a central, vertical section through one type of the newbuffing-wheel;

Figure 2 is a section through the wheel on line 2--2 of Figure 1;

Figure 3 is a similar, central, vertical section through the secondembodiment of the invention; and

Figure 4 is a section on line 44 of Figure 3.

Referring to these drawings, and more particularly to Figures 1 and 2thereof, it will be perceived that in its current most preferred form,the buffing-wheel may be made from an ordinary, straight-face, pulley,modified .or changed to adapt it to perform the necessary functions.

As is usual, such pulley has a central, apertured, supporting hub ID, amiddle, circular web 5 ll outstanding from such hub, and an outer, cy-

lindrical main-body portion I2 supported by the Web, all three parts,I0, II and 12 being of metal, such as aluminum, alloy or the like, andall integral with one another.

55 So far as thus described, the structure is nothing more than that ofan ordinary commercial pulley.

To change or reform such pulley to adapt it to carry the fabricbuffing-elements and to ventilate or cool them in suitable and adequatede- 5 gree, an appropriate number of holes l3 are drilled through thecentral part of the portion l2 at the same time removing some of the webI I, all as is fully and clearly illustrated.

Also a suitable number of holes or apertures l0 l4, M are drilledthrough the part l2 on opposite sides of the medial web II.

In addition, the two opposite margins of the outer face of such modifiedpulley are provided with suitable screw-threads l5 and I6, right and 15left hand if desired, on which may be screwed two collars or round nutsI! and 3 which may have recesses 19 for the accommodation of the prongof a spanner-wrench by means of which the collars or nuts may be screwedand tightened 20 into place.

These collars I! and I8 securely hold or clamp between them the inner,marginal portions of centrally-apertured fabric-bufling-elements 2|, 2|which have a considerable number of radially- 25 disposedventilating-passages 22 in their opposite faces around their centralopenings.

When such metal mounting and its fabric buffing-members have beenapplied to the operating shaft 23 with one end of the hub bearingagainst 30 a shoulder 24 of the shaft and a nut 25 threaded in the endof the shaft and engaging the opposite end of the hub, the buffing-wheelis ready for action upon rotation thereof by the revolution of theshaft. 35

As will be readily understood, during the rapid rotation of thebufiing-wheel, air present at opposite sides of the web, due tocentrifugal force, flows or is forced outwardly through the severalholes l3, I l and through the passages 22 in the 40 sides of thefabric-members, thus adequately and properly cooling the latter elementsagainst the otherwise destructive action of the heat generated by thebuffing-operation.

A somewhat different type of structure is pre- 45 sented in Figures 3and 4 in which case the mounting for the fabric buffing-elementscomprises a hub 3!, adapted to be supported and clamped on thereduced-diameter portion. 32 of the drive-shaft 33, between a collar,34, on the part 32 and bearing against a shoulder 35, and a nut 36screwed on the threaded end portion of the shaft section 32.

As in the previously-described structure, outstanding from the centerof, and integral with, 5

' appliance, holes 44,- 44 may be provided at centers of such grooveswith removal of portions of the web so'that air may directly enterth'ejmiddle portions of such grooves from. .opposite sides of the Web aswell as at their opposite ends.

As will be readily understood, the opencenter; textile-fabricbufiiing-members 45, 45 with perma:

nent, radially-disposed ventilating or cooling passages 46, 46 attheirsides aresupported on the mounting and clamped firmly and securely be-:tweenthereadily-adjustable, threaded collars or nuts 41 4l all as isclearly illustrated, and, when the complete bufling-wheeLas thusconstituted, is rotated at the usual highspeed, air is drawn in throughthe grooves 42, ;42 and is delivered-there- 7 from tothe severalconnecting passages 46, 46

through whichit is discharged outwardly. between the fabriomembers;thereby maintaining the latterat a suitable temperature toprec-ludeundue or damaging heating and burning of the cloth which ';-isperforming the buffing andpolishingaction.

- 1 Those acquainted with'this art will understand that the invention isnot necessarily limited and restricted to the precise featuresillustrated and described and that various modifications may be resortedto withoutdeparture-from the heart and essence of the invention asdefined by the appended claims, which should be construed as broadly aspermitted by the state of the prior art,
